Definitions

  • the invention relates to a sludge suction vehicle with a container connected to a water jet or vacuum pressure pump used as a sludge pump, from whose part of the space receiving the sludge a filter separates a rinsing water space part, from which a low pressure pump supplying the motive water for the water jet pump can also be fed, which in turn can be fed via a Fine filter supplies a high-pressure pump, the fine filter comprising a cylindrical housing with an inlet for the flushing water supplied by the low-pressure pump and with an outlet for returning the thickened dirt to the sludge container, and a pipe arranged in the longitudinal center thereof with a connection for the suction side of the high-pressure pump purified water to be supplied.
  • Such a mud suction vehicle is already known from DE-PS 27 19 599.
  • Such a vehicle is characterized by the fact that its water requirements can largely be met from the water supply that can be carried by itself, which is constantly renewed, so that the work interruptions, as they have to be taken into account in other known vehicles by fresh water tanks at hydrants a generic vehicle does not occur.
  • the fine filter also known as hydrocyclone, as used in this known mud suction vehicle, however, only separates dirt particles with the centrifugal force generated in it, the specific weight of which is significantly greater than water. With frequent switching on and off, such fine filters take a considerable amount of time to reach the optimum operating state, so that even the particles, which are themselves sufficiently heavy, are not separated during these phases.
  • the invention has for its object to improve a mud suction vehicle of the type mentioned so that an even more trouble-free work is possible.
  • the fine filter (hydrocyclone) is liziert as an additional filter in the p. Its mesh size is of course narrower than that of the filter upstream of the rinsing water compartment part. This additional filter closes the gaps in the effective range of the hydrocyclone, which are explained above.
  • Such a filter tube can be designed in such a way that it constantly cleans itself and maintains its filter function evenly by being equipped with a rotary drive and rotatingly sweeping along a scraper arranged in the housing.
  • the mud suction vehicle equipped in this way therefore does not require any work breaks to clean the additional filter. The back from him Dirt particles are easily returned to the sludge container.
  • the scraper extends helically, preferably at the full height of the distance between the housing and the filter tube.
  • the scraper does not stand in the way of a continuous rotation of the rinsing water in the fine filter, but effectively maintains this rotation over the entire length of the housing.
  • a rotation flow also occurs on the outer jacket of the filter tube, which contributes considerably to the self-cleaning of the filter tube and takes the dirt that has been rinsed off there back to the sludge container.
  • a water spray device is used as the scraper, which is preferably acted upon with water from the high-pressure piston water pump.
  • liquid is used instead of a screw-shaped solid body, also known as a doctor blade, with which the meshes of the fine filter body can be very easily rinsed out.
  • a scraper designed as a water spray device does require a constant supply of liquid, but this does not interfere because it is returned to the sludge container within the housing of the fine filter. This makes this water reusable for the immediate removal of the dirt once it has been captured.
  • the water spraying device is acted upon by water from the high-pressure water piston pump, because of which the water filtered from the sludge requires such a high degree of purity.
  • water of such high pressure then all desired spray effects can be achieved on the mesh of the filter tube. In any case, however, it should be prevented that additional dirt particles are pressed into the interior of the filter tube. It therefore depends on the spatial angle at which the spray water hits the mesh of the filter tube.
  • the water spray device is arranged in a spray niche, the side walls of which are used for the rebound of the water jet, it can be sprayed indirectly under rebound from the side walls of the spray niche, so that additional dirt particles are prevented from getting into the interior of the filter tube.
  • the cleaning effect can be increased if the direction of rotation of the rotary drive for the filter tube is opposite to the direction of rotation of the rinsing water in the housing.
  • the sludge receptacle 1 arranged on a sludge suction vehicle is fed with sludge by a sludge pump designed as a water jet or vacuum / pressure pump, which sludge is to be fed from sewers or gullies via hose lines and transported to a landfill.
  • a sludge pump designed as a water jet or vacuum / pressure pump, which sludge is to be fed from sewers or gullies via hose lines and transported to a landfill.
  • the heavier sludge parts settle to the bottom, as is indicated at 2, while a lot of dirty water 3 is kept above it and is separated from the used water accumulated in a space part 14 separated by a first filter 13.
  • This can be fed to a low-pressure pump 4, which, for example, also supplies the motive water for the water jet pump.
  • the mud suction vehicle is equipped with a device for cleaning sewers, water being used under very high pressure, which emerges from a nozzle 7 attached to the beginning of a high-pressure hose and at the same time with its recoil force the nozzle with pulls with its hose through the sewer, the high pressure pump 6 requires a much better filtered water than the low pressure pump 4.
  • a fine filter 5 is used, the basic structure of which is further explained below with reference to FIG. 2.
  • the filter consists of a stationary cylinder 15 as a housing, to which the low-pressure pump 4 feeds the water to be cleaned tangentially at one end at 16.
  • the water rotates, the heavier dirt particles reaching the jacket of the cylinder 15 by centrifugal force and thrown out at the other end at 17 and returned to the sludge container 1.
  • a largely cleaned amount of water remains in the longitudinal center of the housing 15.
  • a pipe is arranged here, which is provided with filter openings 20.
  • the filter tube 10 is designed as a non-open filter tube.
  • the filter tube 10 For constant self-cleaning of the filter tube 10, it is rotatably mounted in the housing 15 about an axis 12 and is rotated by a motor 8, preferably in a direction D (see FIG. 3) which runs counter to the direction of rotation R of the water.
  • a wiper 9 is also provided, which is arranged in the housing 15 and extends helically over the length of the housing 15, namely over the full height of the distance between the housing 15 and the filter tube 10. This also turns on the rotational flow of the water the outer jacket of the filter tube 10 intensified, which contributes to self-cleaning.
  • the housing 115 which consists of a stationary cylinder, is fed tangentially at 116 at one end at 116 by the low-pressure pump 4.
  • the water on the inner wall of the cylinder rotates, the heavier dirt particles reaching the jacket of the cylinder 115 due to the centrifugal force and thrown out again at 117 at the other end and returned to the sludge receptacle 1.
  • In the longitudinal center of the housing 115 largely purified water remains.
  • a tube 110 is arranged at the longitudinal center, which is provided with filter openings 120 and is closed at one end 119. At the other end, the pipe 110 is open and is under suction through the high-pressure water piston pump 6.
  • the filter tube 110 is also rotatably mounted in the housing 115 about an axis 112 and can be rotated by a motor 108.
  • the pipe 110 passes a spray niche 121, in which a spray pipe 122 extends parallel to the axis 112 of the filter pipe 110.
  • the spray pipe 122 is supplied with water from the high-pressure pump.
  • the water jets 124 emerging from the spray pipe 122 first, as FIG. 5 in particular shows, hit one of the side walls of the spray nozzle 121 and are reflected there in the direction of the outer jacket of the filter pipe 110.
  • the spray water flows back into the sludge tank 1 at 117 and takes the detached dirt with it.
  • a water storage chamber 125 is arranged, which is separated from the housing 115 by a partition 126. This means that pure water is immediately available for spraying the filter tube immediately after commissioning.
